I have one that says insert before flight. Makes sense to me because this car flies! Lol
Told I guy I know with a lime green mustang gt and the only one he could get is the one that said remove before flight and I thought it was pretty funny.

Yep. I've seen several places carry those. I imagine one company probably made them up, made thousands at once, and then sold them out to distributors. ...which, probably kept their prices down. You know how it goes.... buy in bulk and the price drops dramatically. We can look into it once we get back from the fest.
